The Turkish pastry filled with cheese or potatoes and often eaten for breakfast is poğaça.
Poğaça is a soft, savory baked bread or pastry found throughout Turkey. It may be made with yeast or other leavening and commonly contains white cheese, potatoes, olives, herbs, or minced meat. Many versions are small and portable, making them a popular breakfast item or snack with tea.
The Turkish name is related to pogača, a broader family of breads and pastries found across the Balkans and Central Europe. The word ultimately traces back through Byzantine Greek to the Latin panis focacius, the source of the name focaccia. Turkish poğaça developed its own local forms, including varieties associated with Istanbul and other regions.
Poğaça is easy to confuse with börek because both can contain cheese or potatoes. Börek is generally made from thin layers of dough such as yufka, while poğaça is usually a thicker, bread-like pastry. Simit, by contrast, is a ring-shaped sesame bread and is not normally filled.
